3. Consider a sterling silver fork weighing 30 g (assume that it is 100% silver for the purposes of this question). Determine the total number of unit cells and number of atoms in the fork. Do not worry about effects of the shape of the fork (I.e. Ignore the fact that some of the unit calls are at the edge of the fork). Silver adopts an FCC structure and has an atomic radius of 0.1445 nm. The density of silver is 1049 g/ cm'. Note: please use the principles we covered in class to solve this
